Hello,
I just want to write my first Python program with a wxPython GUI and I would
like to know if it is possible to get the values of other controls when a
wxButton is pressed ? I have one wxTextCtrl, one wxChoice and three
wxSpinCtrl control from which I want to get the values.
Bye,
Henning
Hi Henning,
Yes, this is possible. Each control has a method to get its value,
usually "myControl.GetValue()", but in the case of wxChoice it will
be "myChoice.GetSelection()". Use these method calls in a function
that you define. (This function will require an 'event' argument).
Then connect this function to the button using the EVT_BUTTON(self,
id=10, myFunction) macro.

Henning,
Here is the example revised with some comments and a RESET button
as well as OK. Cheers.
